[time-nuts] Thunderbolt - Hardware Versions - Performance&Differenences

[Richard W. Solomon]

I looked at the ACE-III on Trimble and do not see mention of a 10 KHz output.
Maybe I miised it, but without it, the N1JEZ board will not do unless you modify
it for 1 pps.
I am trying to find more info, but since it reached EOL, Trimble may have deleted
it.
